A complete documentation in PDF format including source code and schematics is now available to download using the link below:


Source files of this project are available to download using the link below. The ZIP archive contains Z80 assembler sources for the ROM Monitor program, Atmega328 AVR assembler sources and Xilinx XC9536 VHDL source: both for the VGA board.

You can also download schematics for the whole project using the link below. Schematics are in PDF and JPG formats. Filtering caps are sometimes not included in the schematic, but added in final versions of PCBs.

I`m not including Eagle board layout designs as I don`t think anyone would have any use of it – they are rather poorly designed with only one advantage –  they work! 😉

Some examples used in presentations:
